RE is a small, portable, lightweight, and quick, regular expression library for Common Lisp. It is a non-recursive, backtracing VM.

This library provides purely functional dictionaries and sets in Common Lisp based on the hash array-mapped trie data structure.

Common Lisp implementation of Graham Cormode and S. Muthukrishnan's Effective Computation of Biased Quantiles over Data Streams in ICDE’05.

ZPB-TTF is a TrueType font file parser that provides an interface for reading typographic metrics, glyph outlines, and other information from the file.

This package provides audio input and output functions to Common Lisp using bindings to the portaudio library.

This package provides easy access to the defining class and its options during initialization or reinitialization of its subcomponents.

This software provides an interface by which Common Lisp programs can access lexicographic data from WordNet.

generic-cl provides a generic function wrapper over various functions in the Common Lisp standard, such as equality predicates and sequence operations. The goal of this wrapper is to provide a standard interface to common operations, such as testing for the equality of two objects, which is extensible to user-defined types.

This library provides Glib, GIO and Gobject bindings for Common Lisp via Gobject Introspection.

A simple Common-Lisp interface to the underlying operating system. It's independent of the implementation and operating system.

This is a bare-bones Permuted Congruential Generator implementation in pure Common Lisp.

This package provides first-class global environments for Common Lisp.

This is a wrapper for the SDL2_TTF library used for loading fonts and creating text assets. The library, in it's current state, can load TTF and OTF fonts and render fonts with the three different rendering modes provided by the C library (solid, shaded, and blended). While Latin text, UTF8, UNICODE, and Glyph text rendering is available only Latin text has been tested (as shown in the examples).

This package provides a Common Lisp translation library similar to CL-I18N and CL-L10N.

cl-libxml2 is high-level Common Lisp wrapper around the libxml2 and libxslt libraries.

• Interfaces for tree manipulation (like cxml-stp).

• Interface for HTML 4.0 non-validating parsers.

• Specific APIs to process HTML trees, especially serialization.

• XPath API.

• XSLT API.

• Custom URL resolvers.

• XPath extension functions.

• XSLT extension elements.

• Translates libxml2 and libxslt errors to Lisp conditions.

• Extends the Common Lisp iterate library with custom drivers for child nodes enumeration, etc.

• The XFACTORY system provides a simple and compact syntax for XML generation.

This package provides a KDL reader/writer for Common Lisp.

Trivia is a pattern matching compiler that is compatible with Optima, another pattern matching library for Common Lisp. It is meant to be faster and more extensible than Optima.

This library is a fork of SSL-CMUCL. The original SSL-CMUCL source code was written by Eric Marsden and includes contributions by Jochen Schmidt. Development into CL+SSL was done by David Lichteblau.

A Common Lisp library for generating a human-readable diff of two HTML documents.

This is a library that uses the other 3d-* math libraries to present an encapsulation for a spatial transformation. It offers convenience functions for operating on such transformations and for converting between them and the alternative 4x4 matrix representation.

This package is a simple date and time library.

VAS-STRING-METRICS provides the Jaro, Jaro-Winkler, Soerensen-Dice, Levenshtein, and normalized Levenshtein string distance/similarity metrics algorithms.

3D-MATRICES is a library implementing common matrix operations, mainly intended as the counterpiece to 3d-vectors and thus being aimed at operations in 3D space.

This is a Common Lisp autowrapping facility for quickly creating clean and lean bindings to C libraries.
